Title :
Effect of threshold offsets in zero-crossing speech detector

Abstract :
Detectors based on the zero-crossing distribution of a signal can be used to detect speech in a background of noise. The letter shows how, with a low noise level, this type of detector will not operate successfully, and proposes a novel solution to the problem.
